It does look great. The problem with NOS is that they are still over 50 years old. Seals get hard, leak, etc. I could care less about originality, but, there are plenty of aftermarket reproduction shocks that look exactly like the originals, but are modern versions with much better valving inside.

I used to trailer a small boat with my 1968 hard top. I used 2nd gen leaf springs as those cars were heavier. They managed the boat without being too stiff for normal driving.

Have you done the usual tests? Push the rear down and see if it rebounds and stops right away? Load the trunk [on a blanket] with cement blocks and see if it sags? Did the restoration include receipts?
